My Macbook has an error after lid close - lid open:

  • Macbook is on, and music on. Lid close => music stop

  • Lid open, the screen looks like the brightness was decreased to minimal, but the music resumes.

  • Lid close again, this time the music doesn't stop

The only way to quit that situation is reset SMC (Control-Option-Shift + Power)

I have tried the reset of NVRAM (Option-Command-R-P) but no luck.

Reinstall MacOS is also not affect :(

  • this is very difficult to understand, so let me try to modify, if you did no approve you can revert it back. – Ruskes Dec 9 '18 at 6:00
